CAN CLOSING` AND MARKING MACHINE.

Specification of Letters Patent.

Patented oet. 3, 191e.

'Application led December 1, 19.15. Serial No. 64,495.

ing dates, characters or identifying markson the cans in connection with the C an closing operation', the object being to identify the closed cans with the closing operation 1n V respect of any desired data, such as time,

place, agency, nature of the packed product, etc.

The invention consists in the parts and combinations Ihereinafter' set forth and claimed. y

In order to make the invention more clearly understood there are shown in the accompanying drawings means. for carrying the same into practical effect, without limiting the improvements, in their useful application's, to the particular construction which, for the purpose of example, has been ymade the subject of illustration.

In said drawings: Figure 1 isa front elevatio of a portion of a can closing' machine embodying the invention. Fig. 2 is a side View looking toward the right hand end of Fig. 1. F ig. 3 is a perspective view of the.` marking device 'separated from the Fig. 4 is a longitudinal sectional view of the end of the marker lever.

Referring to the drawings, lnindicates a substantially horizontal table on -which the filled cans are supported and along the surface of which they are successively propelled in spaced arrangement to the seaml ing head 2, by an intermittently rotating carrier or turret 3. This carrier 1s mounted on a vertical shaft 4 and formed with canengaging and propelling recesses 5. The cans to he closed are supplied to this carrier (not shown) or manually. The cans are retained in the recesses 5 until they have been operated on by the seaminghead and closed, by an external guide rail G. The can ends are automatically supplied to the top of each W. FLEISCHER,

can before or as it is elevated to the seaminglhead, by any suitable can end feeding device (not shown). The can is so elevated -at the proper instant by a bottom plunger or 'chuck 7 which, afterl the closing operation, descends and leaves the can at the levely of the top of the table 1. A can so elevated into the seaming head is indicated in dotted lines ata.

The succeeding rotation of the carrier 3, with the aid of a deflecting and outwardly curved switch rail 8,\ forces the closed cans outward out of engagement with the carrier, and the cans successively and intermittently push-`one another onto an auxiliary table or support 9 which is attached to and may be considered as a continuation of the table 1. As each can arrives at the position indicated in dotted lines at a it pauses under the marking device in position to be marked or stamped by the latter.

The fixed framework of the machine carries or has attached thereto the tables 1 and 9 and is provided with suitable bearings Afor the operative parts. A portion of said frame is indicated in dotted lines at 10. 11

is the vertical rotary spindle which'carries the seeming head, a bearing for which spindle is indicatedat 12.k 13 is the yoke lever which vertically reciprocates the seaming i head cams 14, which latter cause the radial movement of the seaming rolls 15 in a known manner. 16 is the vertical cani shaft of the closing machine.

-Projecting from the framework of the machine is a horizontal rod 17 having a longitudinal key way 18 therein extending its entire length. This rod has mounted thereon the frame or bracket 19 of the can marking device. which is held against rotation by a key 20 coacting with the keyway in the rod but which can be adjusted along the rod lrelative to the point at which the closed cans pause in their movement yfrom the seaming head. The said bracket is positively locked in the desired position on the rod by means of a set screw'21. I At the outer extremity of the bracket an integral therewith is a. vertical rectangular guide 22. Mounted to reciprocate vertically within this Vguide is a slide 23 having a pivotal connection Q1 at its upper extremity slidably to the .bracket at 32. This spring tends to keep the roller 28 on the rocker arm in engagement with the face of the cam 29. The

rod is vertically adjustable in the swivel by nuts 33 secured on the rod, to provide for adjustment for marking cansv of different heights.

At the lower 'eit'remity ofthe slide is pivoted a type lever holder 34 which is bifurcated to receive the lower end of the slide. T-he fingers of this bifurcated portion extend at an angle to the line of the type holder arm. The inner finger 35 is slightly longer than the outer finger 36 and engages a roller 37 mounted on-a journal 38 which latter is adjustably fixed in a vertical slot 39 in a downwardly projecting lug 40 on the bracket. It will be seen that this journal may be adjusted upwardly or downwardly in this slot and locked in its desired position by a nut 41 on the inner end of the journal. When this nut is tightened it will bind the lug between the nut and a collar 42 on the journal.v

The pivot pin 43 of the type holder lever extends inwardly and terminates in a head 44. Between this head and the longer finger 35 of the type holder is interposed a coiled spring 45. One end of this spring engages the head mentioned while the other eX- tremityv engages the finger 35. This spring acts to normally hold the type holder arm in a vertical marking position over the can, as seen in dotted lines in Fig. 1, the same being prevented from rotating farther than a'vertical position by a pin 46 fixed in the shorter finger of the type holder, which pin engages the sides of the slide rod when the action of the spring 45 has caused the type holder to turn to the before mentioned vertical printing position.

The lower part of the type holder is horizontally recessed and adapted to receive a type bar 47 which in turn holds the rubber stamp or type 48. The type holder has a vertical circular aperture in it designed to hold a coiled spring 49 which bears against the type bar. 'This `construction permits enough give to prevent the face .of the' type from being broken or marred when it comes into engagement with either the can end or the inking roll 50. The inking roll is rotatably mounted on a stud shaft 51 secured at one end to a bracket arm 52. The upper extremity of this bracket arm is slotted at 53 andv is adju'stably secured by This rocker arm has means of a bolt 54 through this slot to a projectin lug 55 on the main supporting bracket o the printing device.

In operation as the cam on the vertical drive shaft revolves it will actuate the rocker arm 27, which in turn, through the medium of the link or rod 25, will vertically reciprocate the slide 23 of the printing device. It will be understood from the above description that as the slide rod descends the action of the coiled spring 45 will cause the type holder to leave the inking roll and keep the finger 35 against the roller until the type holder assumes a vertical position, further action of the spring to throw the type holder out of this vertical position being arrested by the pin 46 coming into contact with the slide. The slide rod and type holder then both descend in alinement, the longer finger 35 leaving its engagement withl the roller, and type 48 perform their printing operation on the closed can end. On thesucceeding half revolution of the cam 29 the roller v28 is depressed (Fig. 1), restoring the parts to non-printing position. It is to be observed tha't the marking impression on the can is performed by a yieldprinting points, where the cans pause as they are ejected from the carrier, cans of different diameters being ejected todifferent stopping points. By the adjustment of the arm 52 or journal 38, or both, the proper inking of the type is insured. The markedcans pass off to a slide or conveyer (not shown) or are removed manually, as is most convenient. The elongated marker-actuating spring 31 hassuch range of action and capacity for yielding 4that no adjustment of the marker up or down, for cans o`f different heights, is necessary in many or most cases. Y

By seaming head I `include various can end attaching means. Such means may be a clencher which crimps the head loosely on to a can, all around the circumference or in spots. Also, when the seaming head is used, only the first operation or curling roll may be put in operation, the complete hermetic seaming by the second operation being done by anyv suitable means after processing the filled andI partly or loosely closed can; and the words closing machine are not limited to a machine which hermetically closes the cans. v
